Has anyone heard of this? 1000 children.
The Dunedin Multidisciplinary Health and Development Study (Dunedin Study) is an ongoing, longitudinal study of the health, development and well-being of a general sample of New Zealanders. They were studied at birth (1972-73), followed up and assessed at the age of three when the longitudinal study was established. Since then they have been assessed every two years until the age of 15, then at ages 18 (1990-91), 21 (1993-94), 26 (1998-99), 32 (2003-2005), and 38 (2010-2012). The Study members are currently being assessed at age 45 (2017-2019) and it is hoped to continue further assessments in the future.
This current study should be interesting hopefully.
The Next Generation Study
The purpose of the Next Generation Study is to look at the lifestyles, behaviours, attitudes and health of today's teenagers, and see how they have changed from when our original Dunedin Study Members were 15 (in 1987-88).
Nothing really current in any of the published studies re transgender; a bit about sexuality and gender. But that should change amonst this present crop of teens, when results are collated, surely?
